II. Background

    The Toxic Substances Control Act (TSCA) (15 U.S.C. 2601 et seq.) 
authorizes the Administrator of the EPA to promulgate regulations under 
TSCA section 4(a) requiring testing of chemicals and chemical groups in 
order to develop data relevant to determining the risks that such 
chemicals and chemical groups may present to health or the environment. 
Section 4(e) of TSCA established the ITC to recommend chemicals and 
chemical groups to the Administrator of the EPA for priority testing 
consideration. Section 4(e) of TSCA directs the ITC to revise the TSCA 
section 4(e) Priority Testing List at least every 6 months.

A. The 50\th\ ITC Report

I. Background

    The ITC was established by section 4(e) of TSCA ``to make 
recommendations to the Administrator respecting the chemical 
substances and mixtures to which the Administrator should give 
priority consideration for the promulgation of a rule for testing 
under section 4(a).... At least every six months ..., the Committee 
shall make such revisions to the Priority Testing List as it 
determines to be necessary and transmit them to the Administrator 
together with the Committee's reasons for the revisions'' (Public 
Law 94-469, 90 Stat. 2003 et seq., 15 U.S.C. 2601 et seq.). Since 
its creation in 1976, the ITC has submitted 49 semi-annual (May and 
November) reports to the EPA Administrator transmitting the Priority 
Testing List and its revisions. ITC Reports are available from the 
ITC's web site (http://www.epa.gov/opptintr/itc) within a few days 
of submission to the Administrator and from http://www.epa.gov/fedrgstr after publication in the Federal Register. The ITC meets 
monthly and produces its revisions to the Priority Testing List with 
administrative and technical support from the ITC staff, ITC members 
and their U.S. Government organizations, and contract support 
provided by EPA. ITC members and staff are listed at the end of this 
Report.
    The 50\th\ ITC Report marks a significant milestone for the ITC. 
Since its first meeting on February 5, 1977, the ITC has convened 
425 meetings, screened thousands of chemicals, and reviewed more 
than 2,500 organic, organo-metallic, and inorganic chemicals to 
identify those with suspicions of toxicity, environmental release, 
and consumer or occupational exposures, but few, if any data (Ref. 
14). In its 50 Reports, the ITC has added to the Priority Testing 
List and recommended testing or information reporting for 81 
individual chemicals and 80 chemical groups (about 1,400 chemicals) 
for priority consideration by the EPA Administrator. In response, 
the EPA has published 200 Federal Register notices and reviewed 
hundreds of test protocols and data submissions and the U.S. 
chemical industry has developed over 1,000 tests and submitted more 
than 75,000 unpublished health and safety studies to the EPA.
    As of 1992, testing was ongoing, proposed, under consideration, 
required or voluntarily conducted for 85% of the chemicals and 
chemical groups recommended by the ITC (Ref. 14). Many of the data 
developed as a result of ITC's recommendations have been 
incorporated into Material Safety Data Sheets, used by U.S. 
Government and industry organizations to develop hazard assessments 
and included in the Organization for Economic Cooperation and 
Development (OECD) Screening Information Data Set (SIDS) dossiers 
(e.g., 100% of the

[[Page 49533]]

chemicals in phase I of the OECD SIDS program were reviewed by the 
ITC prior to preparation of SIDS dossiers), (Ref. 14). Well-known 
examples of chemicals for which data have been developed as a result 
of ITC recommendations include alkyl phthalates, chlorinated 
paraffins and hexachlorobutadiene (Ref. 1), acrylamide, aryl 
phosphates, methylene chloride and trichloroethane (Ref. 2), 
chlorinated benzenes (Refs. 1 and 3), benzidine-, o-dianisidine- and 
o-toluidine-based dyes (Ref. 4), phenylenediamines (Ref. 5), alkyl 
tins and fluoroalkenes (Ref. 6), octylphenol (Ref. 7), bisphenol A 
(Ref. 8), tetrabromobisphenol A (Ref. 9), methyl tertiary butyl 
ether or MTBE (Ref. 10), and brominated flame retardants, including 
brominated diphenyl ethers (Ref. 11).

II. TSCA Section 8 Reporting

A. TSCA Section 8 Reporting Rules

    Following receipt of the ITC's Report (and the revised Priority 
Testing List) by the EPA Administrator, the EPA's Office of 
Pollution Prevention and Toxics (OPPT) promulgates TSCA section 8(a) 
PAIR and TSCA section 8(d) HaSDR rules for chemicals added to the 
Priority Testing List. The PAIR rule requires producers and 
importers of Chemical Abstract Service (CAS)-numbered chemicals 
added to the Priority Testing List to submit production and exposure 
reports under TSCA section 8(a). The HaSDR rule requires producers, 
importers, and processors of all chemicals (including those with no 
CAS numbers) added to the Priority Testing List to submit 
unpublished health and safety studies under TSCA section 8(d) that 
must be in compliance with the revised HaSDR rule (63 FR 15765, 
April 1, 1998) (FRL-5750-4) codified at 40 CFR part 716. All 
submissions must be received by the EPA within 90 days of the 
reporting rules Federal Register publication date. The reporting 
rules are automatically promulgated by OPPT unless otherwise 
requested by the ITC. Under the ITC's VISION and VISP, promulgation 
of HaSDR rules for most chemicals that are added to the Priority 
Testing List has been delayed to allow voluntary submission of 
studies of specific interest (see section II.C. for further details 
on VISION and VISP).

B. ITC's Use of TSCA Section 8 and Other Information

    The ITC reviews the TSCA section 8(a) PAIR rule reports, TSCA 
section 8(d) HaSDR rule studies and other information that becomes 
available after the ITC adds chemicals to the Priority Testing List. 
Other information includes TSCA section 4(a) and 4(d) studies; TSCA 
section 8(c) submissions; TSCA section 8(e) ``substantial risk'' 
notices; ``For Your Information'' (FYI) submissions; ITC voluntary 
submissions, unpublished data submitted to and from U.S. Government 
organizations represented on the ITC; published papers, as well as 
use, exposure, effects, and persistence data that are voluntarily 
submitted to the ITC by manufacturers, importers, processors, and 
users of chemicals recommended by the ITC. The ITC reviews this 
information and determines if data needs should be revised, if 
chemicals should be removed from the Priority Testing List, or if 
recommendations should be changed to designations.

C. Promoting More Efficient Use of Information Submission Resources

    To promote more efficient use of information submission 
resources, the ITC developed the VISP and VISION. The VISP provides 
examples of data needed by ITC member U.S. Government organizations, 
examples of studies that should not be submitted, the milestones for 
submitting information, guidelines for using the TSCA Electronic 
HaSDR Form and instructions for electronically submitting full 
studies. The VISP is described in the ITC's 41\st\ Report (63 FR 
17658, April 9, 1998) (FRL-5773-5) and is accessible through the 
world wide web (http://www.epa.gov/opptintr/itc/visp.htm ). To 
facilitate the implementation of the VISP, the ITC developed the 
VISION. The VISION is described in the ITC's 42\nd\ ITC Report (63 
FR 42554, August 7, 1998) (FRL-5797-8) and is also accessible 
through the world wide web (http://www.epa.gov/opptintr/itc/vision.htm). The VISION includes links to the TSCA Electronic HaSDR 
Form (http://www.epa.gov/opptintr/.er/hasd.htm) including revised 
section 3.2 of the TSCA Electronic HaSDR Form to provide more use 
and exposure information (for details see the 46\th\ ITC Report; 65 
FR 75552, December 1, 2000) (FRL-6594-7).
    The ITC requests that chemical producers, importers, processors, 
and users provide information electronically via VISION on chemicals 
for which the ITC is soliciting voluntary information. If the ITC 
does not receive voluntary information submissions to meet its data 
needs according to the procedures in VISP, the ITC may then ask the 
EPA to add those chemicals to a TSCA section 8(d) HaSDR rule to 
determine if there are unpublished data to meet those needs (see 
section III.A. that requests comments on the need to continue VISION 
and VISP).

D. Coordinating Information Rrequests

    To avoid duplicate reporting, the ITC carefully coordinates its 
information solicitations and reporting requirements with other 
national and international testing programs, (e.g., the National 
Toxicology Program, the OECD SIDS program and the EPA's High 
Production Volume (HPV) Challenge program). The ITC is currently 
focusing its efforts on persistent non-HPV chemicals that have 
bioconcentration and exposure potential, but few, if any, publicly 
available ecological or health effects data. The ITC is working with 
the EPA Persistent Bioaccumulative Toxics (PBT), Endocrine 
Disruption, and perfluoroctylsulfonate chemicals workgroups to 
identify potentially toxic chemicals with few data to complement the 
objectives of those programs.

E. Requests to Promulgate TSCA Section 8(a) PAIR and Section 8(d) 
HaSDR Rules

    The ITC asked the EPA to add 3 chloroalkenes to the TSCA section 
8(a) PAIR rule in its 48\th\ ITC Report (66 FR 51276, October 5, 
2001) (FRL-6786-7). In addition, the ITC asked the EPA to add 5 
chlorinated trihalomethyl pyridines, 2 trihaloethylidene 
bisbenzenes, 4 trichlorophenyldihydropyrazols, and 3-chloro-2,6-
dinitro-N,N-dipropyl-4-(trifluoromethyl)-benzeneamine to the TSCA 
section 8(a) PAIR rule in its 48\th\ ITC Report (66 FR 51276, 
October 5, 2001).
    At this time, the ITC is rescinding its request to add the 3 
chloroalkenes; 5 chlorinated trihalomethyl pyridines; 1 of the 
trihaloethylidene bisbenzenes (benzene, 1,1'-(2,2,2-
trichloroethylidene)bis-, CAS No. 2971-22-4); and 3 of the 
trichlorophenyldihydropyrazols (benzamide, 3-amino-N-[4,5-dihydro-5-
oxo-1- (2,4,6-trichlorophenyl)-1H-pyrazol-3-yl, CAS No. 40567-18-8, 
3H-pyrazol-3-one, 5-((5-amino-2-chlorophenyl)amino)-2,4-dihydro-2-
(2,4,6-trichlorophenyl)-, CAS No. 53411-33-9, and benzamide, N-(4,5-
dihydro-5-oxo-1-(2,4,6-trichlorophenyl)-1H-pyrazol-3-yl)-3-nitro-, 
CAS No. 63134-25-8) to the TSCA section 8(a) PAIR rule, either 
because no production or importation data were submitted to the EPA 
in response to the 1998 Inventory Update Rule (IUR) or because the 
predicted bioconcentration factors (BCFs) were judged to be too low 
to warrant priority consideration at this time.
    The ITC is not rescinding its request to add 3-chloro-2,6-
dinitro-N,N-dipropyl-4- (trifluoromethyl)-benzeneamine (CAS No. 
29091-20-1), 3H-pyrazol-3-one, 5-((2-chloro-5- nitrophenyl)amino)-
2,4-dihydro-2-(2,4,6-trichlorophenyl)- (CAS No. 30707-68-7), and 
phenol, 4,4'-[2,2,2-trifluoro-1-(trifluoromethyl)ethylidene]bis- 
(CAS No. 1478-61-1) to the TSCA section 8(a) PAIR rule.
    At this time, the ITC is also asking the EPA to add stannane, 
dimethylbis[(1-oxoneodecyl)oxy]- (CAS No. 68928-76-7), benzene, 
1,3,5-tribromo-2-(2-propenyloxy)- (CAS No. 3278-89-5) and 1-
triazene, 1,3-diphenyl (CAS No.136-35-6) to the TSCA section 8(a) 
PAIR rule. Stannane, dimethylbis[(1-oxoneodecyl)oxy]- and benzene, 
1,3,5-tribromo-2-(2-propenyloxy)- are being added to the TSCA 
section 8(a) PAIR rule, because they are estimated to persist and 
have predicted BCFs of 8,650 and 4,019, respectively, few toxicity 
data and a need for additional use and exposure data, beyond that 
provided by the manufacturers. 1-Triazene, 1,3-diphenyl is being 
added to the TSCA section 8(a) PAIR rule, because it is a predicted 
carcinogen based on its metabolism and because the ITC needs 
occupational exposure data.
    At this time, the ITC is also asking the EPA to add stannane, 
dimethylbis[(1-oxoneodecyl)oxy]-, benzene, 1,3,5-tribromo-2-(2-
propenyloxy)- and 1-triazene, 1,3-diphenyl to the TSCA section 8(d) 
HaSDR rule. Stannane, dimethylbis[(1-oxoneodecyl)oxy]- is being 
added to the TSCA section 8(d) HaSDR rule, because the ITC needs to 
know if there are other toxicity data in addition to that described 
in section IV.A.2. and 3. of the 49\th\ Report (67 FR 10298, March 
6, 2002) (FRL-6820-8). The ITC needs ecological effects and more 
health effects data; only studies where stannane, dimethylbis[(1-
oxoneodecyl)oxy]- is [ge]90% of the test substance by weight should 
be submitted.
    Benzene, 1,3,5-tribromo-2-(2-propenyloxy)- is being added to the 
TSCA section 8(d) HaSDR rule, because the ITC needs to know

[[Page 49534]]

if there are other toxicity data in addition to that described in 
section IV.A.1.iii. of this Report. The ITC needs ecological effects 
and more health effects data; only studies where benzene, 1,3,5- 
tribromo-2-(2-propenyloxy)- is [ge]90% of the test substance by 
weight should be submitted.
    1-Triazene, 1,3-diphenyl is being added to the TSCA section 8(d) 
HaSDR rule, because the ITC needs pharmacokinetics, genotoxicity, 
subchronic and chronic toxicity, reproductive, and developmental 
toxicity data. Only studies where diazoaminobenzene is [ge]90% of 
the test substance by weight should be submitted.

III. ITC's Activities During this Reporting Period (November 2001 to 
April 2002)

A. VISION

    The ITC is the only organization for which the EPA can 
promulgate direct TSCA section 8(d) HaSDR final rules. As such, when 
the EPA convened public meetings to discuss revisions to the TSCA 
section 8(d) HaSDR rule (63 FR 15765, April 1, 1998) (FRL-5750-4), 
the ITC was invited to provide and respond to comments on this rule. 
One of the most consistent comments by the chemical industry was 
that the ITC should offer more opportunities to provide voluntary 
information submissions (to avoid the mandatory requirements of 
submitting information in response to a TSCA section 8(d) HaSDR 
rule). In response to these chemical industry requests, the ITC 
developed VISP, VISION, and the TSCA Electronic HaSDR Form, and is 
currently evaluating their effectiveness.
    The ITC developed VISP, VISION, and the TSCA Electronic HaSDR 
Form as tools to provide a more cost-effective method for chemical 
producers, importers, processors, and users of ITC-recommended 
chemicals to provide voluntary information. With the exception of 3 
trade organizations, the Alkylphenols & Ethoxylates Research Council 
(APERC), the Color Pigment Manufacturers Association (CPMA), and the 
Ecological and Toxicological Association of Organic Dye 
Manufacturers (ETAD), and 4 manufacturers, 3M Specialty Materials, 
Ciba Speciality Chemicals, E. I. du Pont de Nemours and Company, and 
Rohm and Haas Company, these tools have not been used by chemical 
producers, importers, processors, and users of ITC-recommended 
chemicals. The ITC has received voluntary information submissions on 
<15% of the approximately 500 chemicals for which the ITC has 
solicited voluntary information since implementing the VISP and 
VISION, in effect delaying the ITC's ability to obtain the 
information it needs to make decisions and meet U.S. Government data 
needs.
    The ITC recognizes that there are increasing demands on the 
chemical industry to provide information in response to voluntary 
initiatives, e.g., the OECD SIDS program, EPA HPV Challenge program 
and Voluntary Children's Chemical Evaluation Program (VCCEP). The 
ITC supports and coordinates its voluntary information requests with 
these programs. However, as a statutory-mandated organization 
charged with screening and identifying potentially hazardous 
chemicals, the ITC also recognizes that the chemical industry has 
the responsibility under TSCA and under the principles of 
Responsible Care[reg] and Chemical Right-to-Know, to promptly and 
voluntarily provide information on the ITC's recommended chemicals 
to be used in subsequent hazard, exposure, and risk assessments by 
the U.S. Government organizations represented on the ITC.
    The ITC is considering whether to continue the use of the VISP, 
VISION, and the TSCA Electronic HaSDR Form for chemicals added to 
the Priority Testing List, as the lack of use of these tools has 
resulted in substantial delays in obtaining information that could 
be used to meet the ITC's data needs. The ITC requests comments on 
procedures that could be implemented to make these existing tools or 
other procedures for submitting voluntary information more 
effective. Comments in a word processing file attached to an e-mail 
to [email protected] are preferred, but the ITC will also accept 
comments submitted to Dr. John D. Walker at the address listed at 
the end of this Report by September 30, 2002.

B. DEBITS

    In its 45\th\ through 49\th\ ITC Reports, the ITC described its 
strategies to screen and evaluate chemicals with persistence and 
bioconcentration potential. These activities are referred to as 
DEBITS. DEBITS provides a means to prioritize chemicals for 
information reporting and testing based on degradation and 
bioconcentration potential and availability of effects data.
    Prior to this reporting period the ITC made information 
reporting or testing deferral decisions on 206 DEBITS chemicals. 
During this reporting period, the ITC completed its review of the 
remaining 252 DEBITS chemicals, including the 9 chemicals discussed 
in this section:
    1. Benzene, 1,3,5-tribromo-2-(2-propenyloxy)- (CAS No. 3278-89-
5),
    2. 2,9-Dimethylquinacridone (CAS No. 980-26-7),
    3. 1,2-Ethanediyl tetrakis (2-chloro-1- methylethyl) phosphate 
(CAS No. 34621-99-3),
    4. Oxirane, 2,2',2''-(methylidynetris(phenyleneoxymethylene)) 
(tris- (CAS No. 66072-38-6),
    5. P-cresol, 2,6-di-tert-butyl-alpha-(dimethylamino) (CAS No. 
88-27-7),
    6. Spiro isobenzofuran-1(3H),9'-9H xanthen-3-one, 3',6'-
bis(ethylamino)-2',7'-dimethyl- (CAS No. 41382-37-0),
    7. 1H-indole-2-carboxaldehyde, 2,3-dihydro-2-hydroxy-1,3,3-
trimethyl-(4-methoxyphenyl) methylhydrazone (CAS No. 81241-99-8),
    8. Phenoxazin-5-ium, 3,7-bis(diethylamino)-, (T-4)-
tetrachlorozincate(2-) (2:1) (CAS No. 63589-47-9), and
    9. Oxirane, 2-[2-(4-chlorophenyl)ethyl]-2-(1,1-dimethylethyl)- 
(CAS No. 80443-63-6).
    The ITC is adding benzene, 1,3,5-tribromo-2-(2-propenyloxy)- to 
the Priority Testing List as discussed in section IV.A.1. The ITC 
deferred making a testing recommendation for 2,9-
dimethylquinacridone because its absorption potential into mammalian 
tissues is expected to be low based on absorption data for the 
structurally related EPA HPV Challenge chemical, 5,12-
dihydroquino(2,3-b)acridine-7,14-dione (CAS No. 1047-16-1). 1,2-
Ethanediyl tetrakis (2-chloro-1- methylethyl) phosphate was 
previously removed from the Priority Testing List in the ITC's 
36\th\ ITC Report (60 FR 42982, August 17, 1995) (FRL-4965-6).
    Oxirane, 2,2',2''-(methylidynetris (phenyleneoxymethylene))tris- 
was deferred for testing because its predicted hydrolysis half life 
was 3 days. The ITC deferred making testing recommendations for p-
cresol, 2,6-di-tert-butyl-alpha-(dimethylamino); spiro 
isobenzofuran-1(3H),9'-9H xanthen-3-one, 3',6'-bis(ethylamino)-
2',7'-dimethyl-; 1H-indole-2-carboxaldehyde, 2,3-dihydro-2-hydroxy-
1,3,3-trimethyl-(4-methoxyphenyl) methylhydrazone; and phenoxazin-5-
ium, 3,7-bis(diethylamino)-, (T-4)-tetrachlorozincate(2-) (2:1) 
because of their low-exposure potential. Oxirane, 2-[2-(4-
chlorophenyl)ethyl]-2-(1,1-dimethylethyl)- was deferred for testing 
because it is likely to be tested under one of the voluntary HPV 
chemical testing programs.
    The remaining 243 DEBITS chemicals deferred for testing include 
7 DEBITS chemicals with predicted BCFs <1,000 (see Table 2 of this 
appendix), 28 EPA HPV Challenge program DEBITS chemicals (see Table 
3 of this appendix), and 208 non-HPV DEBITS chemicals with predicted 
BCFs of 3-13 (see Table 4 of this appendix).

A. Chemicals Added to the Priority Testing List

    1. Benzene, 1,3,5-tribromo-2-(2-propenyloxy)- --i. 
Recommendation. Benzene, 1,3,5-tribromo-2-(2-propenyloxy)- (CAS No. 
3278-89-5) is recommended to obtain unpublished exposure, 
environmental fate, health effects, and ecological effects data.
    ii. Rationale for recommendation. Benzene, 1,3,5-tribromo-2-(2-
propenyloxy)- is predicted to persist and bioconcentrate. There are 
very few toxicity data. Depending on the exposure, environmental 
fate, health effects, and ecological effects data that are provided, 
the EPA may consider benzene, 1,3,5-tribromo-2-(2-propenyloxy)- for 
their PBT Initiative.
    iii. Supporting information. Benzene, 1,3,5-tribromo-2-(2-
propenyloxy)- is produced in excess of 500,000 pounds per annum and 
used as a flame retardant for expanded polystyrene insulation board. 
The predicted BCF of benzene, 1,3,5-tribromo-2-(2-propenyloxy)- is 
4,019. The rat oral LD50 was 5 grams/kilograms (g/kg) and 
it was not mutagenic in an Ames assay. A TOXLINE search identified 
one report that benzene, 1,3,5-tribromo-2-(2-propenyloxy)- was 
detected in sewer slime (Ref. 13).
    iv. Information needs. The ITC needs exposure, environmental 
fate, health effects, and ecological effects data. Only studies 
where benzene, 1,3,5-tribromo-2-(2-propenyloxy)- is  90% 
of the test substance by weight should be submitted.
    2. 1-Triazene, 1,3-diphenyl--i. Recommendation. 1-Triazene, 1,3-
diphenyl (diazoaminobenzene) (CAS No. 136-35-6) is being recommended 
to obtain annual production/importation volumes and trends, use, 
exposure, and health effects data.
    ii. Rationale for recommendation. No occupational exposure 
limits have been established by the American Conference of 
Government Industrial Hygienists (ACGIH), the National Institute for 
Occupational Safety and Health (NIOSH), or the Occupational Safety 
and Health Administration (OSHA). Occupational exposures have not 
been characterized and there are no estimates of the number of 
workers exposed. The ITC needs occupational exposure data from the 
uses of diazoaminobenzene, e.g., to manufacture dyes and 
insecticides.
    iii. Supporting information. A recent National Toxicology 
Program Report indicated that diazoaminobenzene is metabolized in 
rats and mice to the known carcinogens benzene and aniline (Ref. 
12). Although not tested for carcinogenicity, diazoaminobenzene is a 
predicted carcinogen based on its metabolism and similarity in toxic 
effects to benzene and aniline. Diazoaminobenzene is used as an 
intermediate, complexing agent, and polymer additive. It is an 
impurity in certain color additives used in cosmetics, food 
products, and pharmaceuticals. It may also be used as a propellant 
for molding of rubbers and plastics and as a coupler to promote 
adhesion of natural rubber to steel tire cords. Since 
diazoaminobenzene has semiconducting properties it may have 
applications in the semi conductor industry.
    Diazoaminobenzene may put workers at a heretofore unrecognized 
increased risk of cancer if they are exposed in the workplace. 
Importation, production, use, and exposure information will assist 
in determining if diazoaminobenzene may need further testing to 
adequately assess potential hazards associated with occupational 
exposures.
    iv. Information needs.--a. Recent non-CBI estimates of annual 
production or importation volume data and trends.
    b. Use information, including percentages of production or 
importation that are associated with different uses.
    c. Estimates of the number of humans and concentrations of 
diazoaminobenzene compounds to which humans may be exposed from use, 
manufacturing, or processing.
    d. Health effects data including pharmacokinetics, genotoxicity, 
subchronic

[[Page 49545]]

and chronic toxicity, reproductive, and developmental toxicity, and 
any human data from occupationally exposed workers. This information 
is needed in order to adequately access the extent and degree of 
exposure and potential hazard associated with diazoaminobenzene.
    e. Only studies where diazoaminobenzene is [ge]90% of the test 
substance by weight should be submitted.

B. Chemicals Removed From the Priority Testing List

    1. Acetone. Acetone was designated in the ITC's 28\th\ ITC 
Report for reproductive effects testing as a chemical with a low 
confidence reference dose or RfD (56 FR 41212, August 19, 1991) 
(FRL-3937-4). Acetone is being removed from the Priority Testing 
List because it was in the OECD SIDS program (see http://irptc.unep.ch/irptc/sids/sidspub.html volume 6) and because it is 
included in the EPA's VCCEP for reproductive effects and 
developmental toxicity testing (http://www.epa.gov/chemrtk/childhlt.htm). The EPA anticipates that under the VCCEP, tier 2 
testing for prenatal developmental toxicity, reproductive and 
fertility effects testing will be conducted for acetone.
    2. Twenty alkylphenols and alkylphenol ethoxylates. The ITC is 
continuing to review data on the alkylphenols and alkylphenol 
ethoxylates that were recommended in ITC's 37\th\ ITC Report (61 FR 
4188, February 2, 1996) (FRL-4991-6), 39\th\ ITC Report (62 FR 8578, 
February 25, 1997) (FRL-5580-9), and 41\st\ ITC Report (63 FR 17658 
, April 9, 1998) (FRL-5773-5). At this time, the ITC is removing 
from the Priority Testing List, 9 alkylphenols and alkylphenol 
ethoxylates from the 37\th\ ITC Report, 7 nonylphenol ethoxylates 
from the 39\th\ ITC Report, and 4 alkylphenols and alkylphenol 
ethoxylates from the 41\st\ ITC Report (see Table 5 of this 
appendix). The rationales for removing these alkylphenols and 
alkylphenol ethoxylates are provided as footnotes to Table 5 of this 
appendix.

  be used to predict toxicity.
2. No domestic production or importation volumes were reported to the EPA in response to 1986, 1990, 1994, and
  1998 IURs or no domestic production or importation volumes were reported to the EPA in response to the July 5,
  2000 PAIR rule (65 FR 41371) (FRL-6589-1).
3. Data developed from testing phenol, 4-(1,1,3,3-tetramethylbutyl)- (CAS No. 140-66-9) in response to the HPV
  Challenge program may be used to predict toxicity.
4. Data developed from testing p-dodecylphenol (CAS No. 210555-94-5) in response to the HPV Challenge program
  may be used to predict toxicity.
5. Data developed from testing branched nonylphenol (CAS No.84852-15-3) in response to the HPV Challenge program
  may be used to predict toxicity.

    There are 10 alkylphenols and alkylphenol ethoxylates remaining 
on the Priority Testing List (see Table 6 of this appendix).

    3. Three DEBITS chemicals from the 46\th\ ITC Report. In its 
46\th\ ITC Report, the ITC discussed 2 groups of DEBITS chemicals, 
polychlorophenols and polychlorobenzenethiols and 
chlorotrifluoromethylphenoxy benzenes (65 FR 75552, December 1, 
2000) (FRL-6594-7). Two of the polychlorophenols and 
polychlorobenzenethiols (pentachlorothiophenol, CAS No. 133-49-3 and 
tetrachloropyrocatechol, CAS No. 1198-55-6) and two of the 
chlorotrifluoromethylphenoxy benzenes (p-toluidine, 5-
chloro-.alpha.,.alpha.,.alpha.-trifluoro-2-nitro-N-phenyl, CAS No. 
1806-24-2 and benzoic acid, 3-[2-chloro-4-(trifluoromethyl)phenoxy]-
, 2-ethoxy-1-methyl-2-oxo, CAS No. 88185-22-2) were subsequently 
added to the Priority Testing List in the ITC's 47\th\ ITC Report. 
All 4 of these chemicals were added to the July 26, 2001 PAIR rule 
(66 FR 38955) (FRL-6783-6). All of these chemicals, except 
pentachlorothiophenol, are being removed from the Priority Testing 
List because no production or importation data were submitted to the 
EPA in response to the 1998 IUR (10,000 pound reporting threshold) 
or the July 26, 2001 PAIR rule (1,000 pound reporting threshold).
    4. Three DEBITS chemicals from the 47\th\ ITC Report. In its 
47\th\ ITC Report, the ITC added 3 chloroalkenes to the Priority 
Testing List: 1,3-butadiene, 1,1,2,3,4-pentachloro-4-(1-
methylethoxy)- (CAS No. 68334-67-8); 3-butenoic acid, 2,2,3,4,4-
pentachloro-butyl ester (CAS No. 75147-20-9); and 3-butenoic acid, 
2,2,3,4,4-pentachloro- (CAS No. 85743-61-9). The ITC is removing 
these 3 chloroalkenes from the Priority Testing List because no 
production or importation data were submitted to the EPA in response 
to the 1998 IUR.
    5. Nine DEBITS chemicals from the 48\th\ ITC Report. In its 
48\th\ ITC Report, the ITC added 5 chlorinated trihalomethyl 
pyridines, 2 trihaloethylidene bisbenzenes, 4 
trichlorophenyldihydropyrazols and 3-chloro-2,6-dinitro-N,N-
dipropyl-4-(trifluoromethyl) -benzeneamine to the Priority Testing 
List. The ITC is removing the 5 chlorinated trihalomethyl pyridines, 
1 of the trihaloethylidene bisbenzenes (benzene, 1,1'-(2,2,2-
trichloroethylidene)bis-), and 3 of the 
trichlorophenyldihydropyrazols (benzamide, 3-amino-N-[4,5-dihydro-5-
oxo-1- (2,4,6-trichlorophenyl)-1H-pyrazol-3-yl; 3H-pyrazol-3-one, 5-
((5-amino-2-chlorophenyl)amino) -2,4-dihydro-2-(2,4,6-
trichlorophenyl)-; and benzamide, N-(4,5-dihydro-5-oxo-1- (2,4,6-
trichlorophenyl)-1H-pyrazol-3-yl)-3-nitro-) from the Priority 
Testing List because no production or importation data were 
submitted to the EPA in response to the 1998 IUR or because the 
predicted BCFs were judged to be too low to warrant priority 
consideration at this time.
